In some embodiments, the knuckle and the stub shaft are both integrally forged or cast.

In some embodiments, the first fastener has a pitch diameter of 265-275mm.

In some embodiments, the heavy-duty independent suspension rim structure further comprises a brake assembly that is a hydraulic disc brake.

In some embodiments, the brake assembly comprises two hydraulic brake calipers, the two hydraulic brake calipers are oppositely arranged on the circumferential side wall of the shaft head, and one end of each hydraulic brake caliper is fixedly connected with the steering knuckle.

In some embodiments, the brake assembly further comprises a brake disc, the brake disc being of solid construction.

According to the heavy-duty independent suspension wheel rim structure, through the design of the split type steering knuckle assembly, the hollow structure shaft head and the hollow structure steering knuckle, the overall structure of the independent suspension is relatively compact while the independent suspension is guaranteed to have higher bearing capacity, and meanwhile, the overall weight of the independent suspension is remarkably reduced. In addition, 1-2 brake caliper assemblies can be optionally arranged according to the characteristics of the use conditions, so that the bearing capacity of the independent suspension is improved, the braking capacity is obviously improved, and the running safety of the vehicle is effectively ensured.
